Prediction of geomechanical changes in faulted rock mass around underground structures subjected to earthquakes
Keywords:
circular tunnel, earthquake, faulted rock mass, stress-displacement state, wave propagation.
Abstract
Faults are a type of geological structure that often leads to geological disasters in underground structures under normal conditions and especially when earthquakes occur, thereby requiring careful study. This article introduces some numerical simulation results on the seismic wave propagation process, on changes in stress and displacement states in the rock mass with a small fault of a dip angle of 45o, around a circular cross-section tunnel, using the discrete
element method (Universal distinct element Code - UDEC)...
